The average number of days needed for the imported crucifer weevil, Baris lepidii Germar, to complete development from oviposition to egg hatch, pupation, and adult emergence was determined at constant temperatures of 15, 19, 21, 23, 25, and 27°C. T

Developmental rates were calculated for all stages of Agrotis ipsilon (Hufnagel). The duration from oviposition to adult emergence is 643 centigrade-degree days at a threshold temperature of 10.4°C.
